Answer:
14 dollars
Step-by-step explanation:
13-6= 7 which is the half he spent so 7 times 2 is 14
Answer:
7y+26
Substitute the variables for the equations and add.
Answer:
The coefficient of variation for <em>A</em> is 24.6%.
The coefficient of variation for <em>B</em> is 33.7%.
Step-by-step explanation:
The coefficient of variation (<em>CV</em>) is well defined as the ratio of the standard deviation to the mean. It exhibits the degree of variation in association to the mean of the population.
The formula to compute the coefficient of variation is,
Consider the data set <em>A.</em>
Compute the mean of the data set <em>A </em>as follows:
Compute the standard deviation of the data set <em>A </em>as follows:
Compute the coefficient of variation for <em>A</em> as follows:
The coefficient of variation for <em>A</em> is 24.6%.
Consider the data set <em>B.</em>
Compute the mean of the data set <em>B </em>as follows:
Compute the standard deviation of the data set <em>B </em>as follows:
Compute the coefficient of variation for <em>B</em> as follows:
The coefficient of variation for <em>B</em> is 33.7%.
Answer:
D
Step-by-step explanation:
A is an arithmetic sequence in that is adds or subtracts the same amount.
B is also an arithmetic is that it takes the original 1000 and adds another 1000 for each year
C is a geometric sequence because it's losing 5× however many questions missed
D is the answer because it says it loses 10% every year, so it loses 10% of the previous year, not the beginning year.
